HOW TO USE AN ENZYME INDICATOR

The preparation and use of Enzyme Indicators is incredibly easy. We offer a technical knowledge centre and full support, including site based knowledge transfer and user training and certification program. Please see the online shop for more information.

PROTAK EQUIPMENT NEEDED

Consumables:

EIs are available in packs of 12 tests. Each pack is complete and includes all the parts needed – with the exception of the actual reader device.

1. Take reagents (ATP AL, Buffer A and ADP reagent) out of fridge and reconstitute ATP SL with Buffer A. Allow to stand for 30 minutes.

2. Turn on luminometer and perform machine self-test.

4. Load three empty luminometer tubes into carousel and close lid. Select ‘INJ. PRIME’ protocol and press start. Reader will now prime each line with reagent.

5. Open lid and remove used luminometer tubes. Luminometer is now ready to measure Protak Indicator Tests.

6. At the end of the testing, or end of each day remove the injectors from each reagent bottle and submerge into washer fluid and perform the luminometer injector wash programme.
The luminometer can be calibrated to the desired frequency using supplied standards.

TESTING:

Unwrap Protak EI Tests at location within area intended for gaseous decontamination. The special design of the holder allows for placement within full loads easily.Record test identifier codes and position of each individual test.To assure complete mapping of the decontamination area we recommend 12 samples per cycle. 4 in the lower quadrants, 4 in the upper and 4 within the load in worst case placements.

SAMPLE RECOVERY AND PREPARATION:

Following the decontamination process dispense each of the tests from their holders into individual luminometer tubes.Simply push the test tube into the custom holder to release the test into the tube.Close tubes and remove from decontamination area.

READING TUBES:

When ready to read EI tests (must be within 12 hours), remove tube lids and load luminometer tubes into the luminometer carousel chain and close lid.Once luminometer is prepared select pre-programmed reading protocol, enter end user I.D. and press ‘Start’.The luminometer will now measure each indicator in less than 1 minute per indicator.Results will appear on screen of connected PC or laptop.

Luminometer software can be programmed to record up to 15 information fields such as individual test identifiers, test positions, cycle type and user and equipment I.D. Analysis functions include calculating mean, SD and CV of test replicates and performing process data trend analysis.
